A: We've noticed this trend too, Chris, and we admire the business model. The more trees you turn into sunglass frames, the hotter the planet gets, the more sunglasses you need. It's what economists call a virtuous circle.

We're kidding, of course, because trees are a sustainable resource. (These days, plastic sunglasses are a sustainable resource too — something's gotta be done with all those empty bottled water containers and more and more sunglass manufacturers are making frames using recycled materials.)

So, yes, it's okay to kill a tree to make sunglasses. Plus, you'll be adhering to the MB principle of organic materials if your frames are made out of wood. If you're looking for something specific, we like Shwood's Oswald frames in walnut. Hand-crafted in Portland, Oregon, they look both sleek and a little artfully disheveled, because they don't quite have that perfectly machined look of plastic frames. We're pretty sure Cary Grant would approve.
